Company email (July 2012):
"The quick answer is that the majority of our beers are vegan. For the most part, our beers use only water, grain, hops and yeast. We don't filter any of our beer. We do use fining agents on a few beers, but we do not use isinglass or any other animal products. Our fining is done using Bio-Fine Clear which is a vegan fining agent.

That being said, we do make beer that isn't vegan. We make several ales that use honey, chocolate, lactose, etc... as part of the recipe. These ingredients are always labelled on the tap wall so the servers/staff knows that the recipe uses non-vegan ingredients. As a company we have always strived to have vegan/vegetarian options and the brewery is no exception. Basically, unless the beers are specially labelled with non-vegan ingredients on the tap wall, they are vegan.

With a seasonal rotation of over 60+ beers annually, I can't list all the vegan beers here for you, but rest assured that all eight "house" beers are vegan.
